Greetings of the time of day,

So, here goes my belated reply...

portmaster will be happy with a MOVED entry and know about the
substitute port, in this situation it got tripped up by
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194870>, i. e.
/usr/local being preferred for linking over the local newly-built libs,
leading to failure during the link stage if the older version is
installed on the same system.

I've had too much trouble with portupgrade to bother with it for the
past five years or so.

We should be aware that poudriere or Tinderbox will *not* find such
upgrading problems for ports-based systems.

So I propose that we amend to the porter's handbook with a
recommendation to always test building an updated port revision on a
live system with the older (previous) port version installed.  Not just
poudriere/Tinderbox.

Hope that helps.

Best regards,
Matthias
